断开内部EMC滤波器
在某些类型的系统上，必须断开内部连接
EMC滤波器，否则系统将接地
（接地）通过EMC滤波电容器的电势，可能
导致危险或损坏驱动器。
注意：断开内部EMC滤波器会增加
传导发射，降低驱动器EMC兼容性
相当地。
下表显示了EMC过滤器的安装规则
用于连接或断开过滤器的螺钉，具体取决于
系统类型和框架大小。

检查组件的绝缘性
驾驶
不要进行任何电压公差或绝缘电阻测试
在驱动器的任何部分，因为测试可能会损坏驱动器。每一个
驱动器已经过主电路和主电路之间的绝缘测试
工厂的底盘。此外，还有电压限制电路
驱动器内部，自动降低测试电压。
供电电缆
根据以下要求检查电源（输入）电缆的绝缘：
连接到驱动器前的当地法规。
电机和电机电缆
检查电机和电机电缆的绝缘，如下所示：
1.检查电机电缆是否连接至电机，以及
从驱动输出端子U2、V2和U3断开
W2。
2.测量相之间的绝缘电阻

Disconnecting the internal EMC filter On certain types of systems, you must disconnect the internal EMC filter, otherwise the system will be connected to ground (earth) potential through the EMC filter capacitors, which might cause danger, or damage the drive. Note: Disconnecting the internal EMC filter increases the conducted emission and reduces the drive EMC compatibility considerably. The following table shows the installation rules for the EMC filter screws to connect or disconnect the filter, depending on the system type and the frame size. The locations of the screws EM1 and EM3 are shown in the diagram on page 43. The location of the screws F1 and F2 are shown in the diagram on page 44.

With 300 mA RCD, consult your local ABB representative. 46 Installing the drive ACH550-01 User's Manual Checking the insulation of the assembly Drive Do not make any voltage tolerance or insulation resistance tests on any part of the drive as testing can damage the drive. Every drive has been tested for insulation between the main circuit and the chassis at the factory. Also, there are voltage-limiting circuits inside the drive which cut down the testing voltage automatically. Supply cable Check the insulation of the supply (input) cable according to local regulations before connecting to the drive. Motor and motor cable Check the insulation of the motor and motor cable as follows: 1. Check that the motor cable is connected to the motor, and disconnected from the drive output terminals U2, V2 and W2. 2. Measure the insulation resistance between phase conductors and between each phase conductor and the Protective Earth conductor using a measuring voltage of 1000 V DC. The insulation resistance of an ABB motor must exceed 100 Mohm (reference value at 25 °C or 77 °F). For the insulation resistance of other motors, please consult the manufacturer’s instructions. Note: Moisture inside the motor casing will reduce the insulation resistance. If moisture is suspected, dry the
